Hi.

You can add new delegates for an event with += and you can remove delegates
from an event by using: -= but is there a way (method) to list all delegates
added to one event???

Sincerely
Greetings

Hi Lore,

Yes, this is possible.
You can use the GetInvocationList() method in your event,
which returns the list of delegates that have been associated with
the event.

MyDelegate[] delegates = (MyDelegate[])MyEvent.GetInvocationList();

Hi, Aravind

Thank you very much.
But it seems this doesn't work with build-in Form-Control-Events for example
this.Button.Click-event?
(EventHandler[])this.button.Click.GetInvocationList();
Doesn't work?!

Or did I do it wrong?
Sincerely
Marane
